php保存信息到当前Session的方法_php技巧

php中可通过$_SESSION保存session变量，下面的代码简单演示了 $_SESSION的用法

<?php
 session_start();
 print("");
 $_SESSION["sitename"] = "W3M";
 print("A value saved in the session named as sitename.\n");
 $_SESSION["MyChoice"] = "red";
 print("A value saved in the session named as MyChoice.\n");
 echo $_SESSION['sitename']."\n";
 echo $_SESSION['MyChoice]."\n";
 print("\n");
?>

上面的代码输出结果如下：

A value saved in the session named as MyLogin.
A value saved in the session named as MyColor.
W3M
red
